Yes, but do you know what the energy meter actually does?
It integrates the real power in time, as follows:
from [0 to 2pi] tan (omega*t)
where omega=2

***pi***f where f the frequency of the mains in Hz (in USA 60 Hz). For your information, one of the slowest possible synchronous speeds (in generators) is 120 rpm, in units powered by two-stroke diesels.You can calculate the number of poles in 50 Hz.One of the smallest diesels available is 15,000 HP,here we have now two 70,000 HP each.The "normal" synchronous speed for two pole generators (say steam turbine) and motors is 3,000 rpm and 2,900 rpm respectively, no matter the size (0,25 kW or 1,25 MW 3~M and say 10 MVA or 353 MVA 3~G).
